The low end of the curve is home to new hires and early-career professionals, as well as experienced and late-career professionals. Regardless, manage all as newcomers to their learning curve. You optimize your team with 15 percent of your people.
Low-end challenges are made more manageable when we can convey to the new hire our vision for the organization and for them within that paradigm.
Invest in frequent, honest communication about what you need and expect from your low-ender, and encourage them to be equally open about what they need from you to develop in their role.
